again occupying it. Ensure the generator is located in

an open outdoor area with the exhaust pointed away

from occupied structures. If anyone experiences

dizziness, headaches, nausea, or fatigue get to fresh

air immediately and seek medical attention.

If the CO DEFENSE light is a constant “orange” then

a system fault has occurred, or it is indicating that it

has reached the end of its life. This fault can only be

diagnosed and repaired by an Authorized Service

Provider.

The CO DEFENSE

monitors the accumulation of CO

gas from all sources in the area around the

generator. If the CO DEFENSE light is flashing “red”

this is not an error and safety measures must be

taken immediately.

Note: Tampering with the CO DEFENSE could result in

hazardous conditions and must be avoided.

Note The generator must not be operated in ambient

temperatures greater than 131

o

F (55

o

handle the rest of the way.

Do not allow the starter handle to snap back against

the engine. Return it gently to prevent damage to the

starter.

AC Circuit Breaker

The generator comes equipped with circuit breakers

that protect the unit and the load from short circuit or

overload conditions. If the circuit breaker opens,

determine why the circuit breaker tripped before

closing the circuit breaker.

CSA Circuit Breaker (If equipped)

240V portable generators sold in Canada come with

an additional circuit breaker that will isolate all outlets

on the panel. This breaker must be in the “On”

position for the unit to provide power.

Low Oil Level Shutdown

The generator is equipped with a low oil level

shutdown that is designed to protect the engine from

damage caused by an insufficient amount of oil in

the crankcase. When the oil level in the crankcase

falls below the safe operating limit, the low oil level

shutdown will automatically shut off the engine.

120 VAC, 20 Amp, Duplex

The 120 VAC duplex receptacle is protected against

overload by a 20 Amp push to reset circuit breaker. It

also provides protection via a Ground Fault Circuit

Interruptor (GFCI) with press to Test and Reset

buttons (RP5500, RP6500, RP6500 E, RP7500 E,

RP8000 E). Use the receptacle to power a NEMA 5-

20, 120 VAC, single phase, 60 Hz electrical load

requiring 20 Amps of current.

Use only high quality, well insulated, 3-wire grounded

to different ambient conditions and other factors such

as fuel quality.

Connection to Household Power Supply

This generator must be installed in accordance with

all applicable local laws and electrical codes. The

generator must be isolated from the utility and the

connection must be verified by a qualified electrician.

Generator Grounding

The National Electrical Code requires generators to

be grounded to an approved earth ground. Correct

grounding for the generator is necessary for optimum

engine performance and reduces the risk of electric

shock. Use the ground terminal to properly ground

the generator. Before using the ground terminal,

consult

a qualified electrician, electrical inspector, or

local authority having jurisdiction for local codes or

ordinances that apply for the intended use of the

AC Usage

Do NOT overload the generator. Exceeding the rated

power of the generator can damage the generator

and the electrical devices connected to it.

Motor-driven devices require a large starting current.

Make sure that the total power requirement of these

types of loads does not exceed the rated power of

the generator.

When the generator is used to power multiple loads

or electric appliances, start by connecting the

appliance with the highest starting power

requirements, followed by the second highest and

ending with the lowest.

High Altitude Kits

At higher altitudes, the standard fuel to air mixture is

too rich and will cause decreased performance and

increased fuel consumption. A rich mixture will also

foul the spark plug and make starting difficult.

Operation at higher altitudes for extended periods of

time may increase emissions.

Proper operation can be ensured by installing an

altitude kit when required. High altitude kits should

be installed by a qualified technician. Contact an

authorized service provider if the portable generator

will be operated at altitudes greater than 3000 feet

(0.9 km) above sea level.

Note: At elevations greater than 8000 feet above sea

level, the engine may experience decreased

performance even with the high-altitude kit installed.
